WASTEWATER TREATMENT
PLANT MODEL AT6 - AT50

• INTRODUCTION
Typical factory-made domestic wastewater treatment plants manufactured by AUGUST IR KO
JSC (hereinafter referred to as the Manufacturer) are designed for domestic wastewater treat
-
ment of a population equivalent to a number of persons from 4 to 50 in private houses, hotels
and boarding houses, restaurants, schools, campers, administrative buildings, etc. (hereinafter
referred to as Units or Unit, depending on context). Water treated in the Units can be discharged
into open water bodies, infiltrated into the soil or used as technical water.
Wastewater is treated in the Units biologically, in a process where microorganisms break down
and digest the contaminants in the wastewater, thus purifying the water. In addition to food,
vital bacterial activity also requires oxygen; therefore, a blower, comprising an integral part of
the Unit, is installed next to the Unit housing.
All household chemicals (detergents, cleaning agents, etc.), if used moderately, are allowed and
do not cause harmful effects on the Unit.
In order to avoid operational problems, it should be ensured that the following substances, to -
gether with wastewater, do not come into contact with the Unit:
• High concentrations of grease and oil products (used oils, lubricants, etc.)
• Toxic or hazardous substances (paints and paint thinners, acids, etc.)
• Biologically non-degradable persistent substances (plastics, rubber, textiles, sanitary napkins,
wood, etc.)
Do not discharge storm water, drainage, pool water or hot water—hotter than 40 °C—wastewa -
ter from farms or animal slaughterhouses into the Unit.
