Water is the essential need in human daily life for health safety, living conditions improvement, national industrialization and modernization. Research and development of the water safety plan for Tan Hiep water treatment plant is necessary and urgent to solve this problems. The aims of water safety plan (WSP) include: • To prevent and control the contamination of the source of its raw water; • To treat efficiency of contamination pollutants in water; • To prevent from re-contamination during storage, distribution and handling; and • Ensure to meet target quality at all processes of the water treatment chain. The aim of this paper was to develop the WSP, personnel organization; writing documents, describing system, calculating, assessing, and forecasting risks through data on water quality, then proposing risk mitigation and protection of technical problems overcome. The results showed that water safety plan has been the correct direction to improve responsibilities of SAWACO in supply clean water from safe, water resource for human. Besides that, this research can provide SAWACO the good measures for prevention from the pathogenous risks raw water resoures.

Background: Better water quality, improved sanitation and sound water resource management will improve public health and economic development in low-income countries. Water safety plan-based risk assessment and risk management from catchment to consumers are the modern and efficient approaches to safe drinking water supply established by World Health Organization. Thus, this paper aimed to assess risk from catchment level to consumers in the community of Brikama. Methods: This study report assessments of risk or hazards from catchment to consumers in Brikama Water Treatment Plant (BWTP), West Coast Region, The Gambia. The various means of data collection used include water quality monitoring, visual field inspection and questionnaire survey to explore data on where the water supply system goes wrong from catchment to consumers, so as to provide an improvement plan. Results: Overall, the day-to-day administration of services at BWTP was very impressive. The fencing of all the 17 boreholes at catchment sites has drastically reduced the risk of contamination including treatment systems and distribution lines. There are less risks observed and constant monitoring of the system was ensured. However, at the consumer end, there are some risks with poor practices associated with water handling, storage and hygiene measures at the household level. Some still use some unclean 20-liter containers to store water and indiscriminately kept drinking cups on the floor and unclean surfaces, and 50% lacked WASH knowledge related to water treatment, such as boiling and filtration at households. The overall perception of water storage, sanitation and hygiene practices could be rated moderately good. Conclusion: The overall findings of this study have shown tremendous achievement in the government's commitment to providing potable water to the people in Brikama Local Government Area. WASH education in the study area is recommended to avoid waterborne disease infections.

Sludge Concentration

The reuse of industrial waste and urban sewage is a vital method for solving the shortage of water resource in China. Settling tank as a processing link in water treatment system widely used exercises a great influence on sewage treatment efficiency, and sludge emissions have a great influence on the operation of water treatment plant. Manual mud and mechanical dredge are widely used in most of the water treatment plants from the current domestic. The design used ultrasonic as a method for determination of sludge concentration, developped corresponding application control software, and finally completed a reasonable and feasible for settling tank intermittent discharge of sludge monitoring and emission control system.The result of our simulation system shows that the program operation is stable and maneuverability, and this set of monitoring on-line and control system has good application and development foreground.

This long-term pilot-scale study on the performance of ceramic microfiltration (CMF) was conducted at the Bangkhen water treatment plant (BWTP), with the raw water from Chaophraya River, Thailand. Raw water turbidity and dissolved organic carbon (DOC) were varied in the ranges of 20–210 NTU and 3.0–8.5 mg/L respectively. The hybrid pilot-scale CMF (Pilot-CMF) operational parameters were optimized with the aid of jar-tests and laboratory-scale CMF (Lab-CMF) operations. The systems were operated with various polyaluminum chloride dosages and filtration cycle times. Pilot-CMF provided excellent steady turbidity removal compared to the conventional water treatment process. DOC removal percentages of Pilot-CMF and the conventional process at the BWTP were 49% and 30% respectively. With different coagulant dosages, unique patterns in transmembrane pressure (TMP) variations were observed. The daily TMP increment under low turbidity conditions was 0.08 kPa/day. During rainy periods (turbidity over 100 NTU) the TMP increment reached 0.79 kPa/day. However, once the turbidity of raw water reaches normal conditions (30–60 NTU at the BWTP) the Pilot-CMF system recovers the TMP increment due to efficient backwashing.
