Combination of Ozone-Zeolite Filter to Reduce COD and Ammonia content in household waste

Abstract

Domestic waste standard parameters according to PermenLH No. 68 Years. 2016 determined one of them based on the pH, COD and Ammonia values. Most household wastewater has these values, so a purification process is required before the wastewater returns to groundwater. One of the treatments carried out is in the form of ozone technology which can decompose organic and inorganic pollutants and kill microorganisms in the waste. The purpose of this study was to determine the quality of household wastewater resulting from ozone bubble treatment combined with zeolite filters. To support the research, we used the pH, COD and Ammonia measurement methods from the treated samples. The method used is in the form of ozone treatment and zeolite filters in wastewater with a variable length of treatment time. From the research results, it can be seen that the combination of ozone and zeolite filter has an effect on decreasing the concentration of COD and ammonia in wastewater.

Horticulture Irrigation Systems and Aquaculture Water Usage: A Perspective for the Use of Aquaponics to Generate a Sustainable Water Footprint

“…A lot of authors only mention in their aquaponic water footprint investigation the water reuse in the production of fish and plant [162] and do not consider the needed water resources for water substitutions, evaporation losses, possible water leaks in the system or the water employed for the animal feed. Also, the water footprint must be defined according to the local climate [202]) and if an aquaponic food production is accurate for certain climates and existents of water resources, taking also into account grey water discharges into the environment [203]. More investigation is necessary about the water footprint in aquaponic food production including the different types of production systems, cleaning and management process to control the different types of water employment and to define if aquaponics is a suitable solution for food production in some rural areas…”
