According to Sharda et al. (2013) investigation, the assessment of the performance efficiency of a full scale brewery wastewater treatment plant, UASB reactor plus aeration (holding capacity of 380 m 3 at HRT of 23 h) followed by sand and activated carbon filter (holding capacity of 15 m 3 at HRT of 1 h) for a period of thirteen weeks showed an overall percentage reduction of COD, TSS and BOD values ranges from 96-98%, 88-98%, and 99% respectively.

How can I optimize the performance of my water treatment plant?
This could be done by focusing on rehabilitating the second residual lagoon, assessing the filter media depths and backwash capacities, and calibrating turbidity-monitoring equipment. Additional modifications to the WTP involving capital improvements may be required to achieve the optimized performance goals on a consistent basis.
What are the requirements of a water treatment plant (WTP)?
It is recommended that the Authority ensure the finished water pH is within the range of 6.5-8.5, effective for treatment processes, and noncorrosive. Capacity Purpose – Assess the major unit process capacities to ensure the WTP can meet water demands.
How many hours a day should a water treatment plant be staffed?
Plant Coverage–A Currently, the WTP is only staffed for eight hours a day; however, the WTP can treat water when operators are not on site. Since the WTP is manually controlled, there would be a delayed response to turbidity spikes or chlorine feed failures when operators are not present at the WTP.
What is a surface water treatment plant?
INTRODUCTION Surface water treatment plants are designed to take raw water of variable quality and produce a high quality finished water on a consistent basis.
What are three critical things you would need to consider when designing a water treatment facility?
Major factors to be considered are: (1) type of the water source, (2) desired finished water quality, (3) skill of facility operators, and (4) the relative size of available funds.
What are the most common variables measured in water treatment?
Parameters that are frequently sampled or monitored for water quality include temperature, dissolved oxygen, pH, conductivity, ORP, and turbidity. However water monitoring may also include measuring total algae, ISEs (ammonia, nitrate, chloride), or laboratory parameters such as BOD, titration, or TOC.
What is accomplished in primary water treatment?
Primary Treatment As sewage enters a plant for treatment, it flows through a screen, which removes large floating objects such as rags and sticks that might clog pipes or damage equipment. After sewage has been screened, it passes into a grit chamber, where cinders, sand, and small stones settle to the bottom.
What parameters are to be used to measure strength of wastewater?
Analytical tests aimed at establishing the concentration (typically in mg/L or ppm) of organic (i.e., carbon-containing) matter have traditionally been used to determine the relative "strength" of a wastewater sample.
What are 5 water quality indicators?
They include dissolved oxygen, pH, temperature, salinity and nutrients (nitrogen and phosphorus).
What are the 7 indicators of water quality?
Temperature, dissolved oxygen, pH, total dissolved solids, conductivity, suspended sediment, nutrients, metals, hydrocarbons, and industrial chemicals are the main indicators that can determine water quality.
What are the 5 stages of water treatment?
Public water systems often use a series of water treatment steps that include coagulation, flocculation, sedimentation, filtration, and disinfection.
What are the 4 steps of water treatment?
4 Steps of Community Water TreatmentCoagulation and Flocculation. ... Sedimentation. ... Filtration. ... Disinfection.
What is screening in water treatment?
Screening is a wastewater pre-treatment, which aims to prevent coarse solids, such as plastics, rags and other trash, from entering a sewage system or treatment plant.
What is BOD COD and TDS?
The most popular sum parameter in waste water analysis are the BOD (biochemical oxygen demand), COD (chemical oxygen demand), TOD or Total Oxygen Demand and TOC or Total Organic Carbon. The TOC reflects the organic pollution on the basis of a direct carbon determination. [ 1] But why does the BOD, COD, TOC, TDS etc.
What are major indicators of water quality wastewater treatment?
The six main indicators of water quality are: dissolved oxygen, turbidity, bioindicators, nitrates, pH scale, and water temperature.
What is COD and BOD in ETP water?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
What is the purpose of multiple treatment processes?
Multiple treatment processes are provided in series to remove turbidity and to remove and/or inactivate cysts and other microorganisms. Each treatment process represents a barrier to prevent the passage and survival of cysts and other microorganisms through the plant into the water supplied to the public.
When was chlorine taken from the DEQ?
On September 3, 2019, chlorine residual samples were taken by DEQ, which indicated an adequate free chlorine residual throughout the south side of the distribution system. While investigating a complaint on September 10, 2019, however, DEQ found inadequate chlorine in the Authority’s distribution system. INTRODUCTION .
