Abstract – water is life to us and all living organism and this water is polluting and scarcity of water is increasing due to large amount of unnecessary use of water. Also the increase of the rate of building construction besides increasing also construction waste so that need of best solution on the treat of waste water and reuse of construction waste. Especially in rural area no awareness about water and effluent water directly discharged into water bodies, due to improper system disturbed our ecosystem. Solution in that problem we design a filter media and utilized construction waste as an ingredient of filter media. So we used Aerobic Brickbat Gravel Sand filter (ABGS) filtration technique and we designed 3 units. After the passing of waste water we seen very excellent results. And the treatment of waste water reuse the treated water for different purposes like horticulture, toilet flushing, car wash, and floor wash etc. also used in construction site for as a curing purpose. In case of grey water the performance of filtration showed overall efficiency are : Biochemical Oxygen Demand ( BOD ) 74.89 %, Chemical Oxygen Demand ( COD ) - 81.85 % , Total Dissolved Solids ( TDS ) - 100% , Hardness - 25.13% , Permanent hardness - 47.22% .And increase the DO and Ph value.
Key Words: Grey water, Reuse construction waste, under gravity Zig-zag flow, Eco-friendly, BOD, COD, DO, TDS.
1. INTRODUCTION Waste water treatment is an essential process to protect our Biodiversity. Water is becoming limited resource in the world. Water shortage and treatment of sewage is become a worrying issue in India. Increasing population and development growth results in producing large amount of wastewater. Which destroying environment and economic problems in the world. More than 70% of our fresh water sources are polluted. Groundwater table goes lower fastly and the population facing the problem of water. So to save water and to increase water table and to produce awareness about wastage of water the government and different NGO’S are working on it. Proper treatment of wastewater is in need of our country. Wastewater treatment management has significant importance with growing population. Wastewaters treatment is opportunity to treat the water and reuse it to avoid problem of water. The wastewater treatment plants are useful for the country. The wastewater © 2022, IRJET

which is treated is useful for many works of government or houses. In future the world will face lot of water scarcity if we can’t avoid the unnecessary usage of water and treatment of waste water and reuse it instead of wasting the water. So that it is very essential to treat the waste water and reuse it for different purposes. Also the world is growing fastly and the population is increasing. Due to increasing population the demand of building construction is increasing. So that the construction industry is increasing fastly resulting a large amount of construction waste is producing such as demolished buildings waste, and demolition materials mostly used as a land filling. So to reduce this waste and to reuse it, we used this constructional waste materials in our experimental model as a filter media. So we can treat the waste water from construction waste and also we can reduce the building construction waste and Reuse the treated water. 1.1 Filtration technique Filtration is a process for removing pollutants from waste water by passing through the filter media. The present experimental setup is based on filtration technique of horizontal roughing filter. Horizontal roughing filters have a large silt storage capacity. It is very useful method to treat waste water which is useful for different purposes. Roughing filter is efficiently removes small suspended particles without forming any chemical reaction and thus it does not form any harmful byproduct. The working model consists four stages that is first settling tank, unit-1, unit-2, and unit-3 and collection tank. Consisting of three units with baffle wall in zig-zag manner each unit. The baffle wall is placed to the travelling time of influent water so that time of contact increased. Filter media consists different constructional waste materials are used such as broken brick bat, broken AAC block pieces, waste course aggregates, ceramic crush, pebbles, hardcoke, coal and cinder aggregates ( industrial waste ) these are easily locally available materials. Unit-1 contains brickbat and pebbles placed such that brick bat are placed starting half portion and pebbles are placed remaining half portion. Unit-2 contains pieces AAC blocks and course aggregate placed same as first unit. The third unit contains ceramic crush, coal, hardcoke and cinder aggregate and the flow is up flow-down flow manner and the media is placed coal, hardcoke and cinder aggregate is placed at the
