Scroll down to Technologies

With a focus on water-, and wastewater treatment, based on the specifications and requirements of our clients, we provide full technological support as follows:

We prefer to start where it all should really begin

Data analyses and process technological support to fine-tune our client’s environmental investment programs, or technical scope of the treatment plants. We do all the necessary comparisons and optimizations among applicable leading technologies. We help our clients to use available budgets at the highest efficiency. We elaborate, compare operational costs, and help our clients to select their solutions with a good consideration of overall lifecycle costs, not only on investment costs.

Development of tailor-designed complex process trains for water- and wastewater treatment

We design all our processes ourselves, focusing on technically challenging complex treatment plants of a larger scale. All our plants and technologies are unique designed process trains, using well-proven process elements. We create optimised process trains to fit budget limitations, considering safety- and ease of operation.

Manufacture and supply of all key process elements

...of our complex custom-fitted process trains. We typically deliver instrumentation and process control systems together with the main mechanical equipment.

We also provide installation supervision and start-up management

With all our clients, we strive for a long-term relationship. In our business sector, plant operation is just as difficult and complex a task, as design and implementation. Our after-sales involvement is indeed the key for clients to sustain well-functioning plants even many years after start-up.

“Let us surprise you with our technologies”

We use our self-developed advanced processes, together with the licensed processes of our Partners.

As a result of our R&D efforts, a new anaerobic process was created to cover a specific application area where well-known high rate processes (slim tower reactors and EGSB-s) have limited feasibility. We combined our vast experience with high rate anaerobic reactors and conventional CSTR reactors. FLORA technology combines the best characteristics of these.

The aim was to develop an anaerobic process, which is suitable for a wide range of high strength warm industrial effluent types containing lots of suspended solids and fats and oils. FLORA can treat these without the need for typical pretreatment for solids-, fat- and oil removal. Simply: “All-In”!

FLORA “All-in” process is capable of degrading both, suspended and dissolved forms of contaminants, at a unique high efficiency (typically above 90% overall COD/BOD reduction). The main features are:

  • Use of high concentrations of flocculent anaerobic sludge, to allow for small reactor volumes and low CAPEX.
  • Unique phase separation system (external, for operational security)
  • Robust, adjustable mixing technology, using multiple mixers
  • Integrated biogas buffer
  • Integrated chemical free desulphurisation

FLORA reactors uniquely combine wastewater treatment, biogas buffering, and biological biogas desulphurization. Three-in-one, allowing for surprisingly low investment costs and simplifying construction and operation. Yet, there are further important advantages, just to highlight a few:

  • Reduction on needs for physical pre-treatment
  • Elimination or, a significant reduction on chemical needs of pre-treatment
  • By elimination of Physical-Chemical pre-treatment, FLORA  also eliminates the production of chemical primary sludge or flotation sludge and all related hassles and high costs for treatment and disposal of these.
  • Instead of having to produce primary sludge or DAF sludge, FLORA degrades all organic components of inlet solids and fats and converts these into valuable biogas.
  • Flat type of reactors allowing for low construction costs and use of any available tank materials (concrete, steel, stainless steel, glass-lined steel).
  • No need for costly, special reactor internals
  • An overall very high COD/BOD efficiency (90-95%), drastically reduces discharge costs
  • FLORA’s high efficiency also reduces or eliminates the need for secondary biological treatment and all related CAPEX and OPEX

Vogel typically offers FLORA for Dairy-, Starch-, Paper industries, Renderies, etc.

The optimized compromise. Combining a small footprint with only minor reactor internals. The unique settling system of the reactor has proven to retain solids also against high upflow rates.

Main features are:

  • Intense mixing of influent and external recirculation, resulting in optimum operational stability.
  • Adjustable up-flow velocity to adapt to specific circumstances
  • Multiple influent lines that can be adjusted individually
  • Completely gas-tight systems: no odour
  • Biogas is collected in the headspace
  • Three-phase separators designed for handling high flows rates

Vogel typically offers the above reactor types for medium-strength, warm industrial effluent types where the majority on COD and BOD is insoluble form. The paper sector, food, and beverage industry, distilleries, ethanol producers, etc. are our typical costumers.

Our high performer slim tower reactors offer best utilisation of reactor volume. Designed to create ideal process conditions. The two-stage settling system enables internal recirculation. Due to this high COD concentrations can be treated and optimum biological conditions are secured.

Main features are:

  • Internal and external recirculation provides optimum dilution, efficiency, and resistance to high inlet fluctuations.
  • Mixing chambers to avoid overloading of the bacteria.
  • Further developed influent distribution system.
  • Able to deal with high calcium concentrations, using unique, heavy sludge discharge points.
  • Polishing section between the upper and lower settling stage.
  • Available both as open top or completely gas-tight

Cyndi® is an aerobic activated sludge process, being the latest generation of sophisticated SBR (sequencing) technologies, featuring some particularly smart elements:

  • Selectable way of infeed (continuous or intermittent)
  • Real-time, respirometry based, sludge activity control system RRC as a key part of the process- and air supply control.
  • Fully simultaneous denitrification, during aeration, without the need of mixers and anoxic zones or anoxic periods.

Cyndi® shows its best advantages when applied for very demanding effluent quality, of low Phosphorous and Nitrogen limits. Among its many competitive edges, we highlight these:

  • Lower investment costs through:
    • smaller tanks, and higher sludge concentration.
    • Compact footprint minimum piping needed.
    • No separate final clarifier, so reduced equipment-, structural-, and piping costs.
    • Simple machinery and instrumentation
  • Low OPEX and Maintenance costs for substantial Life Cycle Cost saving through:
    • Minimum operator attention thanks to highly automatic smart control.
    • Unique low energy demand thanks to lack of mixers and the RRC system.
    • Excellent and stable sludge quality, very well settling sludge (low SVI: 60-90 ml/g).
  • High level of automation and a flexible, very sophisticated process control system, evolved through many years to even automatically handle emergency situations, eliminate human mistakes.

Cyndi® is a cyclic technology incorporating the so-called “selector principle” for well settling, stable, and highly active sludge. We can use versatile tank shapes and the process is very suitable for retrofitting existing outdated technologies, in existing tanks.

Vogel typically offers Cyndi® for biological treatment stage of domestic wwtp-s and as post-treatment of multi-stage industrial treatment plants. It is available from containerised design, small capacities, to large-scale plants of unlimited capacity.

ZLD systems are getting greater attention as useful wastewater treatment as well as water management solutions for complex industrial wastewaters. It is a water treatment process in which wastewater is treated, purified and recycled. The ZLD process completely eliminates liquid discharge from industry thus reduces and eliminates possibility of pollution discharge concerns and regulatory disposal norms.

In case there is no suitable recipient for treated wastewater discharge, or certain effluents are not suitable for the required level of treatment, again ZLD can be the answer.

ZLD- The principle

The principle of “zero discharge” in industrial sector is recycling of all industrial wastewater. This means that wastewater will be treated and used again in the process. Because of the water reuse, wastewater will not be released to the sewer system or surface water.

The ZLD treatment process uses sophisticated, unconventional technologies of wastewater treatment processes to limit liquid waste at the end of your process.

A well-designed, competent ZLD treatment process should be able to:

  • recuperate around 95% of your fluid waste for reuse.
  • handle discrepancies in waste pollution and flow.
  • treat and recover valued by-products from your waste (i.e. salts and brines)
  • produce a dry, solid cake for disposal.
  • The system can accommodate chemical volumes adjustments.

What is the basic components of ZLD treatment system? The exact components of a ZLD treatment system will largely depend on the following:

  1. the volume of dissolved material present in the waste,
  2. the system’s required flow rate, and
  3. what specific contaminants are present.

But in common, a basic ZLD treatment system stereotypically includes:

  • clarifier and/or reactor: to precipitate out metals, hardness, and silica.
  • chemical treatment: to aid help the precipitation, flocculation, or coagulation of any metals and suspended solids.
  • filter press to concentrate secondary solid waste after pre-treatment or alongside an evaporator
  • ultrafiltration (UF) to remove all the undesirable trace amounts of suspended solids and avoid fouling, scaling, and/or corrosion at downstream treatment
  • reverse osmosis (RO) to remove the bulk of dissolved solids from the wates tream in the primary phases of concentration
  • brine concentrators to further concentrate the rejected RO stream (brine) or RO rejects to further reduce waste volume
  • evaporator for vaporizing surplus water in the final phases of waste concentration before crystallizer.
  • crystallizer to boil off any remaining liquid, leaving you with a dry, solid cake for disposal

Because of the wide range of industries that use ZLD and the several waste streams produced, ZLD is a highly customised process, needing in every case substantial engineering input from Customer’s side and from our side as well.
