What is coagulation? What is flocculation? Coagulation is the destabilization of colloids by addition of chemicals that neutralize the negative charges The chemicals are known as coagulants, usually higher valence cationic salts (Al 3+ , Fe 3+ etc.) Coagulation is essentially a chemical process Flocculation is the agglomeration of destabilized particles into a large size particles known as flocs which can be effectively removed by sedimentation or flotation..

Dose calculation-Jar testing. The jar test – a laboratory procedure to simulates the coagulation and flocculation processes to Determine the most effective chemical Determine the most effective dosage Determine the optimum point of application Determine the optimum PH Evaluate polymers.

Choice of coagulants. A number of parameters must be considered: Water temperature, Characteristics of raw water (including calcocarbonic balance). Physico -chemical parameters to include or eliminate priority (turbidity and / or Organic Materials). Operations management (stocks, automation, etc ...) Product cost, Parameters affecting Coagulation and flocculation Water quality ( physico -chemical characteristics especially Alkalinity & Turbidity) Nature and structure of colloids Nature and implementation of used product (Coagulant type). PH Pretreatments Mixing conditions, dose, size & shape of the flocs..

Types of coagulants. Inorganic Coagulants These are often considered to be more cost-effective than their organic counterparts, and they can be applied to a wide variety of water treatment operations including food and drink manufacturing and oil purification. Most commonly used ones are: Ferric Chloride (FC ) Aluminum Sulphate (Alum) Poly Aluminum Chloride (PACL) Organic Coagulants These are typically used for solid-liquid separation when a reduction in sludge generation is required. Organic coagulants can be based on two types of chemistries: Polyamines and PolyDADMAC Melamine formaldehydes and tannins.

Advantages of PAC:. PH Wide range Negligible variation of solution PH when PAC is used Very low need to correct or adjust PH value in case of using PAC. This will dramatically decrease OPEX. Alkalinity consumption & Corrosion causes Compared to conventional inorganic coagulants, Alkalinity will not be consumed, PH value will not be highly decreased and hence corrosion problems shall not arise. Water TDS & Pre chlorination When applying PAC dosage, TDS is not increased There is much decrease of pre chlorination if PAC was used..

Advantages of PAC:. Flocs . & Sludge Fast formation. Large sized. Dense & compact. Residual Aluminum Very negligible . Diseases Prevention. Un-Dissolved TOC Removal Very Effective Iron Fouling Prevention PAC contains no Iron radicals, this helps with Iron fouling prevention in case of being used in RO pr-treatment..

Advantages of PAC:. Low water Temperatures Unlike conventional inorganic coagulants, PAC is still very effective at lower temperatures. OPEX & CAPEX Cost effective. Much OPEX & CAPEX saving. Footprint saving. Handling, Shipping & Storage Very easy to handle. Much shipping & Storage cost saving..

Switching cautions !!!!!. Replacement of Conventional Inorganic coagulants with PACL requires to consider: Complete elimination of the old chemicals ( FC or Alum ) from all tanks & pipelines in order to avoid Aluminum jelly formation (chemical interaction must be avoided) Dosing system must be investigated to make sure It’s not corroded. Flush the old system with water before you apply PACL. System must be checked for any leakages..

WATER ADVANCE TREATMENT CO. LTD.(TWATCO) DTRI The experiment was conducted to evaluate the performance of different concentrations of TWATCO's Poly Aluminum Chloride (PAC 100) as coagulation agent in seawater pre-treatment. The test was carried out at DTRI Pilot Plant in a two Stage media filters with a control test in parallel, where ferric chloride was used as coagulant (as I ppm Fe3*). The duration of the test was 10 weeks, which started on 29th October, 2017 and ended on 18th January, 2018. Based on the test result, it is certified that the performance between ferric chloride (as I ppm Fe3+) and poly aluminum chloride (as 0.5 ppm A13*) is comparable in terms of SDI and there is no significant difference in terms of TOC and turbidity. Moreover, the average residual A13+ in the filtrate was 0.027 ppm. For more details Of th e trial, please to Technicol Report NO• Dr. mad eh Mohammed Alamo Director General, DTRI P.o.
