The company focuses on assembling, designing and consultancy in the field of industrial wastewater treatment on the Czech market. We have developed our own PU membrane  with a special and innovative way of perforation, which ensures the exceptional characteristics of our membrane. We have started supplying these membranes and diffusers to other WWTP producers and thus this additional activity has become the main specialisation of our company.

Aeration membrane PUM 68

The PUM 68 aeration membrane is a polyurethane membrane with specific openings allowing for air release in the form of fine bubbles ensuring aeration of the required medium, usually mixed liquor at wastewater treatment plants.

If there is sufficient volume of blown air and optimal tank bottom coverage with aeration elements, the even bubble distribution results in the medium stirring and sludge is maintained in suspension.

Given the properties of the applied polyurethane, our membrane is highly flexible and resistant which ensures, along with the design and density of perforation, high resistance to the chemical and microbial composition of wastewater as well as automatic drainage and resistance to incrustation.

The membrane features a long service life. Very good oxygen utilisation is reflected in economic operation of aeration systems fitted with these membranes.

Properties:

• Wide aeration operating range
• High oxygen input and oxygen transfer efficiency
• Low pressure loss
• High tear-resistant and abrasion-proof
• Good resistance to oil, gasoline and chemicals common in municipal waste water
• High resistence to microbe and incrustation
• Long service life

Service work

We provide various service work according to the specific needs of the customer. Range of service include namely:

• Replacement of aeration elements
• Overcoating of existing aeration elements
• Or other specific works related to the aeration part of the waste-water plant
