Challenge
挑挑
In many places of the world the production of sweet water e.g drinking water, process water or  irrigation water  from salty
sources such as brackish water
or seawater is the sole possibility for the consumers to get safe and healthy drinking water or treated water for industrial or agricultural use. BHU realises turn-key water treatment projects for medium and large scale customised plants as well as pre-fabricated containerised units for these applications. 在世界各地，通过含盐水，如苦咸水或海水来制造淡水，如饮用水、加工水或灌溉水是让消费者喝上安全健康的水或得到工业及农业用净化水的唯一方法。德国BHU 环境科技公司可以为大中型水处理厂及预制集装箱水处理厂提供水处理交钥匙工程。
Production of Desalinated Water
脱盐水的生产
Desalinated water can be prepared from all kind of salty surface waters, e.g. from brackish water or from seawater. The technologies to be used here fore are safe and secure, and they belong to the state-of the-art. They are based on the following processes:
脱盐水可以从各种地表咸水中提取，如苦咸水或者海水。这里采用的技术是安全的，可靠的，并是当代最新的。这种技术主要基于以下几个步骤：
Pre-treatment:
Oxidation, flocculation, sedimentation (LHPS- Reactor), conditioning, filtration (BiosS-Treat ®- Technology) 预处理：
氧化作用，絮结作用，沉淀作用（LHPS 反应器），软化处理，过滤（BiosS-Treat ®-技术） Main treatment:
Cartridge filtration, high-pressure pumping, energy recovery, low-/ medium-/ high pressure reverse osmosis
主要处理过程：
滤筒过滤，高压水泵，能源回收、低、中、高压反渗透 Post treatment:
pH- adjustment, lime-/carbon dioxide-balancing, disinfection 后处理
调整酸碱度，石灰、二氧化碳矿化平衡，消毒 Auxiliaries:
Filter backwash system, CIP- system, sludge handling 辅助过程
过滤器反冲洗系统，就地清洗系统，淤泥处理
Product Water Quality
生产水质生
The RO- product water will be post-treated according to the individual requirements using the appropriate treatment technologies. Drinking water quality complies with the actual WHO Standards for potable water.
反渗透生产水将会根据客户要求，采用适当技术进行后处理。饮用水质生将符合世界卫生组织设定的饮用水标准。
Integrated Water Facility
水处理综合设备
The advantages of selfish water production can even be maximised by joint design and/or operation of the (drinking) water production facility with the waste water treatment facility and/or other water treatment facilities, such as swimming pool water treatment. By doing so, plant sizes as well as operation and maintenance can be optimised and all kind of water re-use, e.g. for irrigation or grey-water re-use can be achieved. 自我生产水的优势可以通过将饮用水生产厂与废水处理厂或其他水处理厂，如游泳池水处理等进行联合设计或操作而达到最大化。如果这样做，工厂的规模及操作、维护过程都可以得到优化，
Chemical Dosing Unit (SWRO)
化学物质添加装置（海水反渗透）
RO- Stage (BWRO)反渗透环节（水的反渗透）
并能实现各种水质的再利用，如灌溉水或灰水回用。
This calls for serious and competent integrated water engineering, based on respective experience in both, research and design as well as project realisation and operation.
这将会对水综合利用技术方面提出更高的要求，要求操作方必须在两个领域都有经验，包括研究、设计及工程实施、操作等。
BHU Umwelttechnik GmbH can provide this covering water and wastewater technology! 德国BHU 环境科技公司可以为您提供相应的水或废水处理技术！
Benefits of Self Production
自我生产的好处
For medium and small quantity consumers, e.g. hotels, resorts, camping grounds and golf courses on one hand but military installations, industries & construction camps, drilling platforms and ships or catastrophe areas on the other hand, the self production of drinking and process water is an unique, economic and save alternative to water supply from the municipal grid or to water supply by trucks.
对于中小型客户来说，从酒店、度假村、野营营地或高尔夫球场到军事设施、工业及建筑用地、钻探平台、船只或受灾地区等，与市政给水或卡车供水方式相比，自我生产饮用及加工水是唯一经济安全的方法。
Containerised Plants
集装箱式水处理
BHU supplies pre- fabricated RO plants installed in ISO Norm- containers with capacities of 100 to 2.000 m³/d for brackish water desalination and 100 – 1.000 m³/d for seawater desalination plants per container. Larger capacities can be realised by the installation of a series of containers in parallel.
德国BHU 环境科技公司可以在国际标准化组织集装箱内预制反渗透装置。每个集装箱的苦咸水脱盐处理水平可达100-2000 m³/d ，海水淡化处理水平可达100 – 1.000 m³/d 。并置多个集装箱，可相应提高处理水平。
Prefabricated, containerised plants bare the following advantages:
提前预制的集装箱式水处理设备拥有以下优点：
Fast availability of drinking water treatment plant  饮用水处理性能高  Minimal construction efforts required at site  现场建设成本最小化
RO- Plant Fabrication (BWRO)反渗透设备制作（水反渗透）
Safe and secure water supply without interruption
reactor technology
安全可靠水资源不间断
Optimised operation of internal water supply-networks with respect to corrosion and/or precipitation.
内部水资源供应网的腐蚀及沉淀方面操作最优化
No dependency on local water prices
不受当地水价影响
Economic solution.
经济实惠
