Global Zero Liquid Discharge System (ZLD) Industry Was 426.20 Million USD In 2016
Pretreatment and conditioning. Pretreatment is used to remove simple things from the wastewater stream that can be filtered or precipitated out, conditioning the water and reducing the suspended solids and materials that would otherwise scale and/or foul following treatment steps. Typically this treatment block consists of some type of clarifier and/or a reactor to precipitate out metals, hardness, and silica. Out of this process comes a liquid that is then filter-pressed into a solid, resulting in a solution much lower in suspended solids and without the ability to scale up concentration treatment.
Phase-one concentration. Concentrating is usually done with membranes like reverse osmosis (RO), brine concentrators, or electrodialysis. These technologies take this stream and concentrate it down to a high salinity and pull out up to 60–80% of the water.
Evaporation/crystallization. After the concentration step is complete, the next step is generating a solid, which is done through thermal processes or evaporation, where you evaporate all the water off, collect it, and reuse it. The leftover waste then goes from an evaporator to a crystallizer, which continues to boil off all the water until all the impurities in the water crystallize and are filtered out as a solid.
The Zero Liquid Discharge System (ZLD) industry
was 426.20 million USD in 2016 and is projected to reach USD 551.80 million USD by 2022, at a CAGR (Compounded Annual Growth Rate) of 4.40% between 2016 and 2022. The market is driven by various end-user industries, such as Energy & Power, Electronics and Semiconductor, Chemicals & Petrochemicals, Automotive, Pharmaceuticals and others. Before expecting that this expensive and energy intensive technology would be largely employed, businesses will more likely favor better water management, higher recycling rates and effluents discharge control.
The key players are GE Water, Aquatech, Veolia, GEA Group, Degremont Technologies, Mitsubishi, Aquarion AG, IDE Technologies, Praj Industries, U.S. Water, H2O GmbH, Oasys Water, Saltworks, Doosan Hydro (SafBon), Petro Sep and so on. Among them, GE Water, Aquatech and Veolia are the leaders of this market.
The leading companies own the advantages on better performance, more abundant product’s types, better technical and impeccable after-sales service. Consequently, they take the majority of the market share of high-end market. Looking to the future years, the slow downward price trend in recent years will maintain. As competition intensifies, prices gap between different brands will go narrowing. Similarly, there will be fluctuation in gross margin.
As the downstream consumption usually follows with developed and rapid economic growth areas, such as BRICS, the developed areas’ company prefers investing to underdevelopment regions these years. In India, The ZLD market is concentrated in certain locations like Tamil Nadu, Gujarat, Orissa, Maharashtra, and Andhra Pradesh. Stringent implementation of water discharge laws and the social responsibility of the corporate world for environmental clearance will be the major drivers of this market. Low-cost technologies will dominate the ZLD market as currently it is very expensive for widespread adoption, both from fixed and operating cost points of view. Textiles, distilleries and breweries, and power and petrochemicals would be the major end users of this ZLD market. Large pharmaceutical plants in India are required to achieve ZLD.
The industry is expected to remain innovation-led, with frequent acquisitions and strategic alliances adopted as the key strategies by the players to increase their industry presence. Market stays in mature period with a clear concentration. Meanwhile, optimize product mix and further develop value-added capabilities to maximize margins. Manufacturers can take advantage of this situation by reinforcing their production units and supply-chains to avoid any delay in production turn-around-times (TAT) and supply-lead-times.
Significant and lasting barriers make entry into this market difficult. These barriers include, but are not limited to: (i) product development costs; (ii) capital requirements; (iii) intellectual property rights; (iv) regulatory requirement; and (v) Transitions’ unfair methods of competition.
Despite the presence of competition problems, due to the global recovery trend is clear, investors are still optimistic about this area, the future will still have more new investment enter the field. Even so, the market is intensely competitive .The study group recommends the new entrants just having money but without technical advantage and upstream and downstream support do not to enter into this field.
