Lake & Pond Cleaning

SSimple Solution for Lake Management

E P I L I M N I O N The topmost and warmest

layer of water is known as the Epilimnion layer. This layer also contains the highest quantity of oxygen compared to the other parts of the lake. This layer mixes thoroughly withsurface winds and provides fluctuations in oxygen levels. The warm temperatures and higher oxygen makes this layer suitable for a majority of the flora and fauna species of fish.

M E T A L I M I O N The layer between the

epilimnion and hypolimnion is called the Metalimion layer. This layer experiences a rapid reduction in temperature with depth (@ rate of 1 degree per meter). Since the density of water also changes with temperature, the water does not easily rise or sink in this layer. The metalimion layer is also known as the thermcline layer.

H Y P O L I M N I O N The hypolimnion layer is the

lowest layer and is directly beneath the metalimnion layer. This water in this layer is much colder and dense. The stagnant waters of the hypolimnion layer are too deep to be significantly effected by surface winds and currents. Water that is remote from surface influences has a relatively small temperature gradient. In eutrophic lakes, this lower layer of water has no oxygen and is loaded with toxic and decaying materials. The bottom of the lake is known as the benthal.

E U T R O P H I C A T I O N Ponds or Lakes that

support rapid algae or plant growth are termed “eutrophic” ponds. Eutrophication comes from the Greek work for “over fed” and that’s just what plants are when they tend to grow to fast. Such ponds are overly fertile with plant food (mainly nitrates and phosphates).

Dredging and de-silting –

De-weeding/hyacinth control or removal (biological, chemical,

mechanical and manual measures, bio-composting

Bio-remediation (Clean up with bio-products - natural bacteria

breakdown, and aerators to churn the lakes)

Introduction of composite fish culture/larvivorous fish species to control

mosquitoes

Out in the deeper, or limonitic part of the lake the plankton take over. Plankton is a term used to describe those organisms that float freely in the open waters of the lake. Included in this group are the zooplankton (animals) and phytoplankton (algae). Fish, of course, also roam around out here. In a more productive lake the area fish have to roam around gets smaller and smaller as summer progresses. Oxygen in the deeper waters becomes scarcer as dead algae and other detritus rains down into the hypo limnion. Most fish won't be able to survive in dissolved oxygen concentrations less than 5 mg/L.

What To Do Rehabilitating

Flash ObjectiveTo Oxygenate & OxidizeTo remove odor by way of de-odorizing products.To control the growth of Algae & Fungus.To remove bio fouling.To clarify the water column & Pond bottom.

Protocol -1

QUICK FIX PROGRAMME:To treat in combination with Triozon F, CLO2

& CuSO4. 6 Shock Doses & 32 Maintenance doses.To use high power chemical dosing pump

with elongated pipe for treatment @1 meter above Pond bottom level. Floating Service to be Supported by Dept.

Area of treatment to be spot decided subject to contaminant level.

Protocol-2 {Bottom Aeration} The installation of a pond bed

aeration oxygenates the water at the bottom, and eliminates the hypolimnion by low cost, low powered, continuous destratifcation of the thermal layers. The whole idea of aeration is to get oxygen into the deep water. Aeration with tiny air bubbles from bottom up and circulation of lower water layers helps to achieve uniform levels of oxygen and temperatures throughout the lake. Once the lake or pond is full of oxygen near the bottom, new insect larvae, snails and other fish food can begin to live at the bottom.

PROTOCOL-3 {BIO-ENZYME}A good lake is one, which

contains fresh; sparkling clear, sweet smelling water and which supports fish life free from excessive algae and weeds. Biotechnology based

solutions involve the use of scientific methods to aintain the

natural health of lake. The Essential components of a good Biological solution are:

(A) The presence of a sufficient quantity of beneficial facultative bacteria

(B) The provision for sufficient Pond/Lake Bed Aeration

Be-AwareBeing Chemical dosing utmost care should be

taken while handling the products. Egg Has to be handled like egg. Glass has to be handled like glass.

Visible eruption of entrapped Algae will surface up, post treatment. Either this has to be remove manually, or flushed out thro outflow source.

Public & Press has to be kept informed that State is in process of cleansing the lake, hence for couple of weeks this situation is inevitable for good.
