7 FILTRATION DAYLIFF CX RANGE

8 FILTRATION DAYLIFF CXD RANGE Higher pressure range Used for chemical media Automatic valve options -available soon

9 DAYLIFF FC RANGE Mild Steel Standard & Deep Bed SS on special order Higher pressure Special media Manual control valve FILTRATION

10 PENTAIR PXD INDUSTRIAL FILTERS Automated operation with Pentair Electric Control. Deep Bed configuration for specialized water treatment media applications. Structural Fiberglass pressure rated at 10 bar. High efficiency internal flow arrangement for even filtration and effective backwash.

11 Activated Carbon Reduces: color and odor Organic chemicals Birm speeds up reaction between DO and Iron/Manganese. Aqualite removesheavy metals and can filter down to 20mic Activated Alumina Fluoride content by adsorption SPECIAL RESINS

12 ULTRAFILTRATION

14 DAYLIFF ULTRAFITRATION

15 ADVANTAGES OF ULTRAFILTRATION

16 PENTAIR LINE GUARD Operating Conditions - Max. Inlet Pressure: 4 Bar; Water Temp Range: +10C C; TSS: <0.1mg/l; Turbidity: <0.3 NTU Membrane Area: 4.5m2 Flow Rate: Initial flow rated at 60l/min (3.6m3/hr); Compact unit 2No. modules mounted on a panel with the control unit installed in between. Produces pure water and removes >99.9% of all of bacteria, viruses, cysts as well as sediment and turbidity; No pre-treatment or other chemical processes required

17 AQUASENTRY MANUAL UF Removes particles, bacteria, cysts etc Uses hollow fibre membrane Based on simple gravity principle Standalone or in parallel connection Low cost, no power, no chemicals 10,000litres per day

18 APPLICATIONS OF ULTRAFILTRATION Surface Water Treatment Post treatment of Waste Water /Effluent water RO Pretreatment

22 DOSING SYSTEMS

23 ELECTRICAL DOSING Seko AMM/AML Standard unit Dosing Range 5-lit/hr Grundfos Alldos Higher Flow Rates Grundfos Quality & Reliability

24 Ngethu Treatment Works

25 PROPORTIONAL DOSING Dosatron Range Proportional Dosers Powered Only by Water Pressure Dosing rate proportional to flow rate Sizing by flow rate on line and percentage of the dosage required

26 KLORMAN INLINE DISINFECTION 500,000lt per cartridge at 1ppm with no chlorine demand

27 BUCCANEER IN LINE DISINFECTION One charge of 6 refill cartridges will dose 8,000 m3 to 1 ppm free chlorine

28 KLORMAN & BUCCANEER APPLICATIONS Food processing facilities Shelf life enhancement Potable water disinfection Environmental hygine Pre and post harvest Medical facilities Animal kennels

29 APPLICATIONS EXAMPLE

30 PACKAGED PLANTS Dayliff WG and WP plants Complete packaged plants for treatment of water from surface sources Dosers for flocculation and chlorination Sedimentation basin Sand filter Dayliff WG 50 plant

31 PACKAGED PLANTS Dayliff WP Plant Control panel WP sedimentation tank Dayliff WP 500 plant Dosing pump & tank Dayliff CX 500 filter

32 REVERSE OSMOSIS

33 SYSTEM BLOCK DIAGRAM FEED PERMEATE CONCENTRATE

34 WHY USE PRE-TREATMENT? RO is designed to filter out dissolved solids not suspended solids. Pre-treating the feed water will increase the life and recovery of the membranes. In the long run you will SAVE money if you pre-treat. GOOD PRE-TREATMENT = GOOD RO PERFORMANCE

35 WHY PRETREAT THE WATER Scaling Precipitation of solutes onto membrane surface Occurs at tail end Heavy metals, H2S, Silica, Hardness etc Fouling Growth of bacteria on membrane surface forming slime layer Occurs throughout membrane COD & BOD Clogging Deposits of silt in membrane Throughout membrane but most common at front. Metal Oxides, TSS (colloids, clays, silts, etc.) Membrane Degradation Chlorine damages RO membranes

37 WASTE WATER TREATMENT PLANTS D&S Reaching the Next Level

38 BIOLIFF WATER TECH: BIOROCK WWTP BIOROCK is a revolutionary compact WWTP system. No need for power. No moving parts. Silent operation. Minimal maintenance. Ease of handling and installation Suitable for domestic applications D&S Reaching the Next Level

39 SBR WWTP Bioliff SBR wastewater treatment plants use the Sequential Batch Reactor process. SBR process provides for full Carbon and Nitrogen removal - produces high quality effluent. SBR Process: a) Primary Treatment b) Secondary Treatment - Aeration, Biodegradrading and Settlement and Storage; D&S Reaching the Next Level

40 BENEFITS Highly Stable Fixed Film Technology Incredibly Versatile but also Simple Excellent process control Robust Process Survives difficult conditions e.g. power cuts, flooding, toxic shock, poor design Low sludge wasting frequencies Quick delivery times (under 1 month possible) Modular configuration allowing for scaling up Customizable design Enpura Process: a) Primary Treatment b) Buffer Tank c) Aeration Reactor d) Clarifier Tank e) Storage Tank c) ENPURA WWTP D&S Reaching the Next Level

41 MOBILE WATER TREATMENT PLANTS D&S Reaching the Next Level

42 CONTAINERISED SYSTEMS- PAE UF & RO D&S Reaching the Next Level
