Test strips are your guide throughout the water treatment process, with a chart to measure Chlorine, PH, and Alkalinity. If your PH and Chlorine are in the proper range indicated by the chart, your alkalinity should balance. After adding the proper chemicals, wait approximately 15 minutes and retest.

How is surface water made safe to drink?
There are several methods for treating surface water and professional advice should be sought for the design and installation of a water treatment system to remove any contaminants that may present a health risk. These treatment methods may include: Filtrationto remove particulate matter and some dissolved material from water.
What are the methods used in surface water treatment?
Two processes are commonly used to treat surface water: - Conventional treatment including clarification (coagulation/flocculation, sedimentation or dissolved air flotation), sand filtration, activated carbon adsorption and disinfection. - Advanced treatment based on ultrafiltration technology.
What are the 5 steps of water treatment in order?
These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.

What is the correct order of water treatment?
The water-treatment process involves four steps, in this order: coagulation, sedimentation, filtration, and disinfection.
What are the 7 methods of water treatment?

When water and flocs undergo the treatment process, they go into sedimentation basins. ... Filtration. ... Disinfection. ... Sludge Drying. ... Fluoridation. ... pH Correction.Nov 7, 2015
What are the 3 stages of water purification?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment.Dec 6, 2018
What is aeration in water treatment?
Aeration treatment consists of passing large amounts of air through water and then venting the air outside. The air causes the dissolved gases or volatile compounds to release from the water.Aug 23, 2019
What is screening and straining?
Screening and straining devices trap trash and coarse debris using smaller apertures such as grates or screens.Jan 18, 2022
What is first step of raw water treatment?
Coagulation. Coagulation is often the first step in water treatment. During coagulation, chemicals with a positive charge are added to the water. The positive charge neutralizes the negative charge of dirt and other dissolved particles in the water.
What are the steps to purifying water?
The 4 steps of water treatment are: coagulation and flocculation, sedimentation, filtration, and disinfection. Some bottled water companies take extra steps to disinfect their water with uses of purification techniques such as ozone treatment and ultraviolet lights.
How many stages are there in water purification?
The ideal setup in terms of the cost and performance perspective is 4 stages: sediment filtration, carbon filtration, reverse osmosis, and the post taste refining filter.
What is the second step of water treatment?
The second step is called flocculation, in which larger particles called flocc form after coagulation. Sedimentation occurs next when the heavy flocc settles to the bottom and is cleared away.
What is the first step in surface water treatment?
When water enters a treatment plant [see also Water Treatment ], the first step is coagulation, the rapid mixing of coagulants such as aluminum sulfate, ferric chloride and organic polymers into the water.
Why is aeration used in water?
Aeration, the mixture of air with water, sometimes is used if undesirable amounts of iron and manganese are present; the elements remain in solution in water in the absence of oxygen. Aeration is done primarily to improve the aesthetics of water: color, taste and odor.
Why is fluoride added to water?
In some systems, fluoride is added to reduce tooth decay. California law requires fluoridation of water in systems with 10,000 or more connections. State officials say 30 percent of all public water providers in California fluoridate their water.
What is activated carbon used for?
Activated carbon also may be used to remove chemical contaminants. Rather than being trapped in the small passageways between grains of sand, contaminants stick to the surface of carbon and are removed, a process known as carbon adsorption.
What is TOC in RG-379?
See Guidance in RG-379, Total Organic Carbon (TOC) Guidance Manual for testing related to the requirements for total organic carbon, which must be reported on the SWMOR-Alt for plants that include sedimentation as a unit process.
What is a TCEQ watch?
TCEQ's Drinking Water Watch holds the information we have for your public water system and is open to the public. This has contact information, sample sites, sample results, violations, and public notice due dates.
What is alternate technology?
Alternate technology is defined by the Long Term 2 Surface Water Treatment Rule ( LT2) . The LT2 allows systems to receive credit for treatment other than the conventional types (such as coagulation, flocculation, sedimentation, media filtration, and disinfection using chlorine or chloramine).
Do surface water treatment plants need to update their concentration time?
Surface water treatment plants occasionally need to update their Concentration-Time (CT) studies and to submit additional reports and information when the plant has performance problems. Additional forms, instructions, and guidance for these and other topics can be found on Monitoring and Reporting for Surface Water Systems.
