Lamps UV

• Disinfection with UV rays is an ecological methodof water disinfection.

• The result of the applicationof ultraviolet is tasty and healthful drinking waterboth in the water network and customers

Application:• Disinfection (drinking water, municipal

wastewater, process water, ballast water)• Destruction of residual ozone• Reduction of chloramines in pool water• Cosmetology• Pharmaceutics

Types of UV lamps

Medium pressure lamps

Type: InLine

Low pressure lamps

Type: ProLine

Purate is the new technology to produce chlorine dioxid

PURATE – stabilized mixture of sodium chloratewith hydrogen peroxide – patented by a firm EKA (AKZO NOBEL) – the biggest producer of sodium

chlorate in the world.

Mechanism of producing chlorine dioxide – ClO2:

NaClO3 + ½H2O2 + ½H2SO4 = ClO2 + ½Na2SO4+ ½O2+ H2O

PURATE

Application of Purate:

Industrial Water

Potable water

Paper industry

Water in cooling circulation

SERVICE

To our clients we offer a full scope of service.

Science department

• The company AQUA SEEN has also ascientific background.

• We are implementing an innovativesolutions for environmental protection.

Science department – example of our innovative implementations

1. Drain system SE-LOP Type XA

The main innovative element of Se-Lop drain system is a filtration drainage (slotted sieve) made of 100% from stainless steel 304 (equivalent OH18N9), with 0,2 mm and reversed triangular shaped slots. Total surface of slots in a drainage depending on a type of a triangle wire varies between 8% and 10% of a drainage surface.

2. FWAThe Filter work Analyzer enables us to provide a reliable control of the filter quality. Turbidity measurement analyzes only parts with the row size 0,2 µm, and consequently when appear parts with bigger size,the turbidity measurement will notshow any changes.
