AS-IDEAL PZV 2-10 E0
An ideal wastewater treatment plant constructed under the notification
duty and discharging to subsurface infiltration systems
The AS-IDEAL PZV wastewater treatment plant is particularly suitable in places, where it is not possible to discharge cleaned wastewater to sewers, water streams, agricultural drains, etc. It is designed for family houses, hotels, boarding houses and other various facilities.
The advantages of the AS-IDEAL PZV (WWTP) and its AS-Klärmax IDEAL built-in section are as follows
•“Ideal”wastewatertreatmentplantuponthenotificationduty•Robusttank•Simpletechnologywithwell-proven,highreliabilityandefficiency•Sludgeproblemssolved•Samplingwithoutdifficulties•Possibilityofsanitizationattheplantoutlet•Potentialuseofcleanedwaterforirrigationpurposes•Possibilityofremotesupervisionoverthewastewater treatmentoperations•Thepricesincludestheinletconduitandthecover•Advantageouspriceforanotification-dutyPZV-typeplant
