Excel VBA deleting rows based on an if statement (speed up) - excel

Question

I am deleting rows based on the value in column P.
Cells in column P have an if statement: IF(K<10,0,1)
If the value in column P is 0, then the row needs to be deleted.
I am using the following macro which works but takes quite long.
I would like to beable to process about 10000 rows.
It would be much appreciated if I could have some suggestions on speeding up this code.
[I had tried using this if statement: IF(K<10,"",1)
And then deleting rows using SpecialCells(XlCellTypeBlanks) but the the cells are not interpreted as blank , due to the presence of the formula I presume. ]
Sub RemoveBlankRows()
Application.ScreenUpdating = False
'PURPOSE: Deletes any row with 0 cells located inside P
'Reference: www.TheSpreadsheetGuru.com
Dim rng As Range
Dim blankrng As Range
Dim cell As Range
'Store blank cells inside a variable
'On Error GoTo NoBlanksFound
Set rng = Range("P2:P30000") '.SpecialCells(xlCellTypeBlanks)
'On Error GoTo 0
For Each cell In rng
If cell.Value = 0 Then
cell.EntireRow.Delete
'Value = ""
End If
Next
Application.ScreenUpdating = True
End Sub

Answer 1

This looks for 0 and avoids blanks:
Sub RowKiller()
Dim rKill As Range, r As Range, rng As Range
Set rng = Range("P2:P30000")
Set rKill = Nothing
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Application.EnableEvents = False
For Each r In rng
If r.Value = 0 And r.Value <> "" Then
If rKill Is Nothing Then
Set rKill = r
Else
Set rKill = Union(rKill, r)
End If
End If
Next r
If Not rKill Is Nothing Then rKill.EntireRow.Delete
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
Application.EnableEvents = True
End Sub
This is only demo code. Tailor it to meet your needs.
