health, poor water, the most precious possession of human, better water, better life. seawater is the most precious gift given by the nature. seawater desalinization relates to our survival and development in the future. we have the world leading reverse osmosis water process in technique in the first stage and second stage free treatment. different combining schemes are adopted due to different water quality when water enters first past reverse osmosis. energy recovery system is used to convert energy for supplying pressure demanded if necessary, the water will enter a second pass, reverse osmosis for processing post mineralization can also be added to meet drinking requirement. finally, transport the high quality, pure water to fresh water cake to complete a set of integrated purification system. h w t t has been shouldering the mission of benefiting mankind. does we concentrate on research and development of water treatment technology and insist on technological innovation to contribute to be fresh water utilization through fifty years of efforts, we have become the biggest e p c general contractor and hand the biggest seawater desalinization base in china, which equipment capacity has reached seven hundred thousand tons per day. we have concluded a set of full solution service from our successful experience of fifty years, including consultation, design, purchase, engineering, assembly, construction, project management and personal training, to help you solve all problems in engineering. intimate, full solution service is reflected in every person of the team. we strictly check every link and choose the best solution scheme on the basis of your real situation in project construction to optimize processing lower costs and enhance progress during project operation. we will provide you with systematic operation training, routinely maintained it to reach the expected goal, high efficient and stable seawater. desalinization system fulfills our promises in many industries, such as municipal administration, power industry and part of water. h w t t established long term cooperation relations with world famous enterprises in dozens of countries and regions in asia and the middle east. there you can see the busy figures of our engineers in the front line. we provide you with all around height, quality service in professional artists, efficient service, ideas of more owners, more responsibility for us, information and encouragement. we believe that your satisfaction is our biggest seek good life with the respect for water. h w t t will always witness brighter smile with you. develop water treatment, technology benefit the whole society, better water, better life.
