What do we do? Delivering brine management and zero liquid

discharge (ZLD) technologies for water production processes, wastewater treatment and gas&oil production.

What is Brine? Brine is a byproduct liquid waste with high levels of

salinity. Brine is usually generated by large scale industrial processes, primarily desalination.

The Market Main growth engines:

(a) stringent regulations enforcing water reuse&recycling and ZLD practices. Financial&insurance companies as well as manufacturers must also comply with regulations and international treaties aimed to enforce sustainable approach. (b) The growing use of membranes in desalination and wastewater treatment processes generate vast amounts of byproduct brine that requires economical and environmentally sustainable disposal and created a considerable market for brine management technologies.

Target Markets: Desalination, Mining, Gas&Energy and industrial processes involving membranes (pharmaceutical, food&beverage, microelectronics etc.). The market is estimated at nearly $1 billion!

The Need Lack of cost effective solutions – while membrane

technologies, particularly reverse osmosis, have developed significantly and are widespread in recent years, there are few or no cost-effective brine disposal methods and technologies.

Threat on land development in inland locations - Following decades of continuing expansion of seawater desalination capacity at coastal sites, considerable interest has now shifted to inland water sources. Innovative and cost effective brine technologies will provide growing communities with fresh water and industrial plants with sustainable disposal options.

About the Company

Lesico CleanTech is developing and commercializing advanced desalination solutions and sustainable brine management technologies, primarily desalination rejected brine.

Lesico Cleantech has contractual relationships with Ben Gurion University (BGU) and the Zuckerberg Institute for Water Research (ZIWR) – leading water research institutes with extensive research activities in diverse water sciences, and with Mekorot – Israel's national water company.

Lesico CleanTech was selected as one of the top 50 water technology companies in the world by the Artemis Project for its leading game-changing technologies that provide venture grade investment opportunities in the water sector.

Product Portfolio 1. WAIVTM (Wind Aided Intensified eVaporation) – A state-of-the-art enhanced evaporation

technology for brine volume reduction/minimization. The device is operated by the wetting of evaporation surfaces, mounted on suitably constructed modules.. The device uses the driving power of the wind, which drives away excess humidity from the surfaces to intensify the evaporation process by a factor of 15-20 X more than a conventional evaporation pond! See appendix 1.

2. Modular Electrodialysis – A breakthrough customary stack structure with modular design, low hydrodynamic resistance and particle tolerance. The new ED unit is aimed for pretreatment for reverse osmosis to develop a different hybrid for Zero Discharge Desalination (ZDD). The new design will allow significant improvement of water production rates and will inherently reduce capital&operational costs of brackish water desalination and brine volumes. See appendix 2.

The Business Model Beta Sites – Operating beta sites in key regional markets with strategic partners, research centers

and opinion leaders in cooperation with local regulatory authorities. Go to Market Strategy – Sales in target markets throughout distributors, strategic and channel

partners with a commercial platform. Exit Strategy – M&A or IPO

Intellectual Property (IP) Strategy A firm "Intellectual Capital Management" with processes and measures (official patents,

trademarks, trade secrets and know-how) which supports the company's business strategy. NOT a list of patents and patent applications but a proactive plan that is mainly aimed to protect

Appendix 1 – Wind Aided Intensified eVaporation

A state-of-the-art enhanced evaporation technology for brine volume reduction/minimization. The device is operated by the wetting of evaporation surfaces, mounted on suitably constructed modules. A pump brings the water from small holding pond or storage tank to a distribution network on top of the vertical surfaces from which the vertical strips are fed by gravity.

The device uses the driving power of the wind, which drives away excess humidity from the surfaces to intensify the evaporation process by a factor of 15-20 X more than a conventional evaporation pond!

largest brackish water desalination plant

How Does it Work? 1. Holding pond from which WAIV is fed

2. Pump to lift brine to perforated pipes which distributes it to wetted surfaces

3. Wetted surfaces from which brine evaporates

4. Impervious surface (concrete) sloping back to pond to allow excess brine to return to pond by gravity

Appendix 2 – Modular Electrodialysis

Electrodialysis: Background

Electrodialysis (ED) is a relatively mature desalting technology: it was invented before Reverse

osmosis (RO). The potential advantage of ED over RO is its applicability in very high salt

concentrations as well as in brackish water, since no high pressures are required for the process.

Since ED, unlike reverse osmosis, removes salts from the feed water, and not water from the

solutes, it is particularly advantageous for the treatment of brackish water containing relatively

low amounts of salt. Hence ED can serve as a high recovery desalination system and to solve the

crucial currently expensive unsolved problem of brine disposal in the desalting of brackish water.

The conventional ED stack consists of an array of parallel flat sheet membranes: alternating anion-

exchange and cation-exchange membranes, known as cell pairs. The array is held in a filter-press-

type structure. The feed water flows through the compartments created by these membranes,

and the direct current which is passed through the stack, concentrates and dilutes the alternating

"brine" and "diluate" compartments, respectively. In order to keep the total electrical resistance

low, the compartments should be as thin as possible, usually 0.5-1 mm. Clearly, leaks between

the two types of compartment must be avoided. Leak-free sealing is achieved by accurate design

and structure of spacers and gaskets, substantial and carefully balanced pressure applied by the

end elements of the press, and by specially designed entrance and exit ports of the

compartments. The narrow ports may lead to clogging, which should be avoided. A large fraction

of the hydrodynamic resistance of the conventional ED stack is due to these ports. This extra

resistance increases the pumping energy necessary for fast enough flow of the feed water.

In currently available commercial ED equipment (figure 1.3), the cost of the membrane stack is a

large part of the total initial investment. The filter press concept, the expensive membranes and

the gaskets all contribute to the high cost of the stack. A less expensive stack would make the

process more competitive, facilitate desalting of additional saline water sources, and help in

achieving the goal of Zero Liquid Discharge (ZLD) by reducing the large volumes of concentrated

brines. A simplified stack would also make operation and maintenance of the plants less

complicated.

The innovation of the new ED design:

Our new design concept (figure 1.4) is based on sealed modules allowing free flow of solutions within the stack, new polymer membranes that can be sealed to each other and ion-conductive spacers that reduce polarization. The new stack has no gaskets and no holes, and thus we do not fight the leaks around holes, and there are no thin (0.3) channels. The hydrodynamic resistance is due only to the compartments themselves and not to entrance/exit ports.

with many inlet and outlet ports leading to

high electrical resistance, clogging and high

maintenance costs
