discharge standard of the ballast water , therefore, the Shijiyuan company according to the emissions standards of the international conventions' require , after years of research trials, in May ,2011 launched the first automatic ballast water filter and the ultrasonic medium pressure UV sterilizer, and by the unit in charge of the inspection certification. Shijiyuan ballast water uniformly available, which shows good practicability, economy, applicability, hopefully in the future with great market advantage, and make more contributions for the protection of the marine environment and promote the development of the world shipping industry.
 
Our corporation has gainde compliments home and abroad, due to the stability and liability of the products and specialized technological service thus cooperates well with others. We aim to become the world leading company and hope to have a long-term cooperation with friends from home and abroad for mutual development.
 
 
优盈APP下载压载水过滤机 
产品简介Product brief introduction
优盈APP下载压载水过滤机是在双级智控压差过滤机基础上开发研制的一种具有多种功能的优盈APP下载综合性水处理设备;它采用过滤精度可达2微米的高强度316L不锈钢烧结膜,集优盈APP下载高压反洗和超声波清洗杀菌技术于一体,无需更换滤元、清洗彻底无死角、自动运行、自动反洗、自动排污,同时具有超声波杀菌灭藻、消毒、阻垢、降低COD和防止滤网污堵等多种功能。系统运行安全可靠,维护方便,运行费用低。
Automatic ballast water is a multifunctional integrated automatic water treatment equipment which is developed based on the Double Intelligent Pressure Differential Filter. It uses up to 2 microns filtration precision high-strength 316L sintered stainless steel membrane, set against automatic high-pressure wash and ultrasonic cleaning sterilization technology in one, and do not need to replace the filter element, clean thoroughly and no dead ends, automatic operation, automatic back wash, auto emissions, but also has ultrasonic bath sterilization, disinfection, reduce COD and prevent filter fouling and other features. It is widely used in municipal sewage, domestic water, oil field injection water filtration, metallurgy and food, landscape and farming industries. The system safe and reliable operation, easy maintenance, low operating costs.
             
工作原理Working principle
原水由进水口进入机体,首先以外压方式流经粗滤网,滤除较大颗粒性杂质。粗滤网出水以内压式进入细滤网,进一步截留水中的细小杂质,同时,超声波同步工作,对液体中的微小气泡核产生振动,当声压达到一定值时,气泡将继续膨胀,然后突然闭合,这些小气泡急速崩溃时在气泡内产生了高温(5000K)高压(上千个大气压),并且由于气泡周围的液体高速冲入气泡,而在气泡附近的液体中产生了强烈的局部激波,也形成了局部的高温高压,从而产生了超声的杀菌、清洗、粉碎、乳化、分散、阻垢、促进化学反应等一系列的作用。频率在20KHz以上的超声波集高级氧化、焚烧、超临界氧化等多种水处理技术于一身,不但能防止滤膜污堵,延长滤膜反洗周期,同时具有显著地杀菌和降解有机物的功能。
随着过滤介质中各种污染物在细滤网内侧的累积,过滤通道被堵塞,进出水口压差逐
