Optimal wastewater treatment technologies are a good topic for controversy. Dispose of and remove contaminants by various methods. There are enough novelties on the market. Undoubtedly, evolution is in the direction of symbiosis of physicochemical and biological methods. Membrane methods have become loud and are actively developing. Promising technology under the power of tasks that used to solve long, difficult and costly.
Remvodplast Plus is closely monitoring scientific achievements in the field of treatment facilities. He has been designing water treatment facilities since 2006. The company has many strong arguments:

•  The world-famous manufacturer and supply partners are a world-famous manufacturer such as Alfa Laval.
•  Business architecture includes a set of works – from design to commissioning and maintenance of the facility.
•  ‘Behind the shoulders’ a lot of implemented projects. Their activities are in the field of view: help, analysis, extraction of lessons continue.
•  The company attracts grants and loans at low interest rates for the reconstruction of treatment facilities. Collaborates with many financial structures, including foreign ones.

‘RVP Plus’ professionally designs and builds structures for water treatment facilities. Performing a cycle of work ‘with one hand’ reduces the technical and financial risks of the customer. There are few companies in Ukraine that solve problems comprehensively.

Implemented objects are the best reputation

Effective treatment facilities in Eastern Ukraine are the main achievements of Remvodplast Plus.
The next step is a number of orders in other regions. The company is proud of the commissioned projects. Information about them – on the site ‘Remvodplast Plus’. The advantages of the implemented solutions were assessed by customers from the cities of Luhansk, Kurakhovo, Krasnoarmeysk and others.

Partners

New products patented by Alfa Laval combine the interests of a potential customer and the engineering company RVP Plus. Alfa Laval employs 16,000 people around the world. Areas of interest are global issues. Including wastewater treatment. Municipal water, which has been filtered on Alfa Laval equipment, is drunk by 200 million people. Proprietary cleaning systems introduced +1000 industrial facilities in 2015. RVP Plus and a world-renowned concern became partners in Ukraine. The Alliance opens favorable horizons for customers.

What is attractive about collaboration with Alfa Laval?

the latest technologies. Measures – hybrid biomembranes: filtration and biochemical oxidation in one vial. Membrane bioreactor was born at the intersection of sciences: analytical chemistry, hydrogas dynamics, microbiology. The membrane in the unit is a physical barrier for particles, including the smallest viruses, in addition to its surface there is a biological treatment of activated sludge. Having studied the existing ICBMs on the world market, Alpha Laval proposed her concept of filtration modules. Hollow Sheet polylistovye membranes – company development.

Advantages of bioreactors with Hollow Sheet:

• Do not use vacuum pumps. Filtration is in gravitational mode with a low transmembrane pressure of 1-4 mbar. No moving parts.
• Washed with chemical reagents 3-4 per year (when purification of wastewater).
• Membrane elements are higher and wider than existing on the market. Tightly packed in a floor structure – this increases the filtering ability.
Depending on the actual condition and composition of wastewater, a typical capacity of 10-30 l / h per m2. Alpha membranes

Laval is made in its own production – the quality is perfect. The design of the IBE is compact, simple, easy to maintain. Low energy consumption. The quality of cleaning is higher compared to traditional methods.

New Deals in Alfa Laval with Purification

The ISO Disco fabric filter is another innovative step. The plate technology system resembles a membrane module. In a static design the washing carriage moves. When the level of the solution in the tank increases, it begins to move on the outside of the fabric, pumps out the contamination with vacuum. Each disk filter is isolated from others, acts autonomously. Productivity range 7.9-16 m3 / h / m2³/ time / m². productivity 7.9-16 m3 / h / m2.
Input parameters:

• The average amount of suspended solids is 20-30 mg / l;
• The maximum amount of suspended solids is 50 mg / l;
• The average value of BOD is 20 mg / l. Output parameters:

– the average number of suspended solids 3-5 mg / l;

– the average value of BOD 3-5 mg / l.

Advantages of ISO DISC pre-cleaning technology:

• The design is simple, compact;
• does not require a separate tank – install in the channels of treatment facilities;
• Uses electricity sparingly. To wash the filter with a capacity of 12 thousand m3 / day, use a centrifugal pump no more than 10 kW with a capacity;

Dehydration of precipitation with low energy consumption.

As a result of operation of the equipment Alfa Laval with insignificant consumption of electricity receive a dry KEK and a pure joint. The company proposes to include drum thickeners and gravitational tables in the technological cycle. With an energy consumption of 1.5 kW per 90 m3 / h, the concentration of the condensed phase at the finish will be 8-10%. Dehydration on the decanter is possible without the addition of reagents.
Decanter centrifuges, improved by engineers Alfa Laval, consume 10-40% less energy than competing technologies. Some patented solutions reduce electricity costs to 0.5 kW per m3 of treated sludge.
Alfa Laval offers to dehydrate different types of sludge on tape and chamber filter presses. Screw units are used to reduce the noise load – if this factor is important for the object.

The company ‘RVP Plus’ offers the reconstruction or construction of new treatment plants according to European standards and technologies.

Modern objects include mechanical cleaning complexes, membrane bioreactors, innovative sediment dehydration systems. We guarantee the use of advanced technologies and new products of the world cleaning market. Promises assistance and takes responsibility for technical solutions supplier of equipment Alfa Laval. This fact guarantees the customer confidence in the reliability, payback of treatment plants. We invite potential customers – municipal water utilities and wastewater treatment companies for mutually beneficial cooperation.
